竞争吸附剂对负载型常温精脱硫剂上活性组分的分散作用与表征

Dispersal Effect and Features of Competing Absorbent on Fine Desulfurizer of Loading Metal Oxide under Normal Temperature

用浸渍沉淀法制备复合金属氧化物脱硫剂 ,添加竞争吸附剂可以使金属氧化物在载体γ Al2 O3上高度分散 ,有利于其与硫化物反应 .常温、缺氧条件下精脱H2 S穿透硫容可达 16 8% .分析了竞争吸附剂的分散作用机理 ,采用EP。

By adding competing absorbent to the loading metal oxide desulfurizer,which was prepared through impregnating depositing,can make metal oxide highly disperse on the support of γ Al 2O 3,and be propitious for acting with sulfide.Under ambient temperature and no oxygen,its sulfur capacity of removing H 2S reaches 16 8%.The dispersion of active ingredient on support and the variety of microsurface fore and aft desulfurizing are analyzed with EP and TEM.
